Enter an equation of a chemical reaction and click 'Balance'. The answer will appear below. Always use the upper case for the first character in the element name and the lower case for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Compare: Co - cobalt and CO - carbon monoxide.
3.5 mol NaOH x (1 mol Cu(OH)2 / 2 mol NaOH) = 1.75 mol Cu(OH)2. Now, we can calculate the mass of Cu(OH)2 produced using its molar mass: ... (163.0 g of Fe2O3) has 1.02 moles and sample c) (150.0 g of BaO) has 0.98 moles. So, the correct answer is b. ... Find the probability that the number rolled is greater than 3. Express your answer as a ...
\[ moles \, glucose = 45.3 \, g \, glucose \times {1 \, mol \, glucose \over 180.2 \, g \, glucose } = 0.251 \, mol \, glucose \nonumber \] 2. According to the balanced chemical equation, 6 mol of CO 2 is produced per mole of glucose; the mole ratio of CO 2 to glucose is therefore 6:1. The number of moles of CO 2 produced is thus

Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4 {2-} or NH2NH3 {+}. Enter just an element symbol to show the common and uncommon oxidation states of the element.
27 kwi 2023 · N2(g) + 3H2(g) → 2NH3(g) (4.2.3) (4.2.3) N 2 (g) + 3 H 2 (g) → 2 NH 3 (g) This equation shows that ammonia molecules are produced from hydrogen molecules in a 2:3 ratio, and stoichiometric factors may be derived using any amount (number) unit:
To calculate the number of moles of an element use the formula: n = m/M, where m is the Mass of the element, and M is the Molecular weight. The mass of one mole of a substance is equal to its molar mass in grams.
